Lots of comments about what the union should and shouldn't have done.
Instead of whinging on a website, why not get up and do something about it?
The union is made up of it's members. The branch executive is elected by those members to represent them. They act as an executive and do not consult and ballot on every issue. They have done nothing different here.
If so many people think they know a better why to conduct industrial relations, stand for election and show the rest of us how it should be done.
